Leak from reg vent - the 'gat'

Recently picked up my first angel, must say I'm quite impressed. But, it has developed a small leak from the vent hole on the hpr. I've replaced the orings on the mini reg housing, lubed them, and reinstall'd. The leak persists and am curious to know if it could be caused by something else or if the orings I'm using have to be the problem.

Leaks from the vent hole 99% of the time are caused by the reg spool o-rings. It's easy to get really tiny nicks in them when re-installing due to the threaded portion at the bottom of the foregrip housing, so don't rule that out just because the o-rings are new. Use plenty of grease on them. Large piston o-rings would be the next thing to check.

Removing the circlip from the reg becomes exponentially easier with a pair of circlip pliers. You can find them at just about any hardware or automotive store. If you plan on keeping this gun for any appreciable amount of time it'd be well worth picking up a pair. Make sure you get ones designed for internal circlips. The ones designed for external circlips are spring loaded to splay the clip out when squeezed - you want exactly the opposite. A pair of mini needle nose pliers will also work, although the clip has a tendency to want to slip off sometimes with them.

I don't see the ball bearing. Is it still in there?? That should go in first before the rest of the guts.

It was in the housing still, but good looking out

I replaced the out side orings again, and lubed the others. I turned the reg with the threads when installing it this time. Now leak free almost certain I got a small cut the first time, like you said.
